> Fails about 35% of the time in the GCE build. Let me attach a picture from 
> current flakies dashboard for branch-2.
> The test starts a cluster of three RS w/ 3 region replicas. It then stops a 
> server, starts a new one, and then expects that the remaining three nodes do 
> not have instances where two region replicas have landed on a single server.
> It fails sporadically (reproducible locally) because when the SCP runs its 
> assign, sometimes timing has it so Master knows of two servers only.  Making 
> the new start before the old one is stopped (instead of other way around) 
> seems to fix the test -- there'll be three servers up when SCP runs.
